The multi-way circuit may operate with a controller and the base modules of a lighting control system to provide a fully functional, multi-way toggle circuit, even when the switches installed in the base module are not paired or in their off modes. The multi-way toggle circuit can be defined as follows: if any button in the circuit is pressed (indicating a desire to change the load state), then the load toggles its state between on and off.

DETAILED DESCRIPTION

Following below are more detailed descriptions of various conceptsrelated to, and exemplary embodiments of, inventive systems, methods andcomponents of lighting control devices.

FIG. 1A is a perspective partially exploded view of a lighting controldevice 100. The lighting control device 100 includes a switch module 102including a light switch actuator 106 and a tactile display 104 housedin the light switch actuator 106. The lighting control device 100 alsoincludes a wall plate cover 108 including a switch module opening 110extending there through. The lighting control device 100 also includes abase module 112 configured for coupling to the switch module 102 viamulti-pin socket 114. The base module 112 is sized and configured forreceipt within a one-gang wall electrical box and has a volumecorresponding substantially thereto. The base module 112 is configuredto be coupled to a wall electrical box via connection tabs 116 andfastener apertures 118 in the connection tabs 116.

The light switch actuator 106 includes an outer actuation surface 122,which as discussed further herein may be composed of glass. Theactuation surface 122 is movable, for example, by pushing on the curvedfoot 120 to cause the light switch actuator 106 to pivot, for example.The pivoting of the light switch actuator 106 and the actuation surface122 causes a contact component (shown in FIG. 2) of the switch actuator106 to move from a first position to a second position. Movement of thecontact component causes a connection of an electrical flow path, forexample by allowing two electrical contacts to connect or by connectingthe contact component with an electrical contact. The connecting of theelectrical flow path permits electrical energy supplied by a powersource connected to the base module 112 to energize or activate thetactile display 104, as discussed in further detail herein. The tactiledisplay 104 is structured in the switch module to move contemporaneouslywith at least a portion of the actuation surface 122 and with theactuator 106. When activated or energized, the tactile display 104allows a user to define or select predefined lighting settings where thelighting settings change the voltage or power supplied to one or morelight fixtures. The change in power supplied to the light fixtures mayinclude a plurality of different voltages supplied to each fixture andmay be based on various parameters including, but not limited to,location, light intensity, light color, type of bulb, type of light,ambient light levels, time of day, kind of activity, room temperature,noise level, energy costs, user proximity, user identity, or variousother parameters which may be specified or detected. Furthermore, thelighting control device 100 may be connected to all of the lights in aroom or even in a house and can be configured to operate cooperativelywith one or more other lighting control devices 100 located in a unit orroom and connected to the same or distinct lighting fixtures.

FIG. 1B is a fully exploded view of the lighting control device 100 ofFIG. 1A. As demonstrated in FIG. 1B, the tactile display 104 ispositioned between the outer actuation surface 122 and the light switchactuator 106. The actuation surface 122 may be composed of animpact-resistant glass material permitting light from the tactiledisplay 104 and/or a clear sight of path for sensors 127 or otherlights, such as a light from light pipe 126 indicating activation topass through the actuation surface 122. The tactile display 104 iscomposed of a polymer-based capacitive touch layer 124 and a lightemitting diode panel 125, which are controlled via one or more modulesor processors positioned on the printed circuit board 129. The tactiledisplay 104 is housed within a recess 131 of the light switch actuator106 beneath the actuation surface 122. The light switch actuator 106 maybe formed as a thermoplastic housing including a housing cover 133 and ahousing base 135. The light switch actuator housing cover 133 ispivotally connected to the housing base 135 via pins 136 and the housingcover 133 is biased with respect the housing base 135 via torsion spring137. In particular embodiments, the light switch actuator housing cover133 may be configured to slide or otherwise translate or rotate. Theouter actuation surface 122 is biased with the switch actuator housingcover 133 and moves contemporaneously therewith in concert with thetactile display 104 housed in the cover component 133 of the lightswitch actuator 106. The light switch actuator 106 includes a switch pin128 movable between positions to close an open circuit on the primaryprinted circuit board substrate 150, which board also houses a switchcontroller or processor. In certain embodiments the light switchactuator 106 may include a circuit board stack, including the primaryprinted circuit board substrate 150 and a secondary printed circuitboard 138. The light switch actuator 106 may include a latch 136 forcoupling to the base module 112 (e.g. as the light switch actuator 106is passed through the opening 110 in the wall plate cover 108), whichlatch causes the light switch actuator 106 to click into place. Thehousing base 135 includes a multi-pin connector or plug 134 configuredto engage the multi-pin socket 114 of the base module 112.

The lighting control device 100 includes a mounting chassis 142configured to be installed to an electrical wall box. The mountingchassis 142 creates an even surface for installation of the othermodules (e.g., the base module 112 and the switch module 102). Once thebase module is connected to the electrical wall box via the mountingchassis 142, the wall plate cover 108 can be coupled to the mountingchassis 142 and the light switch actuator 106 can be inserted throughthe switch module opening 110. In particular embodiments, the wall platecover can be coupled to the mounting chassis 142 and/or the tabs 116 ofthe base module via magnets. The magnets may be recessed within openingsof a portion of the wall plate cover 108. As noted, the base module 112is configured to be coupled to the mounting chassis 142 via connectiontabs 116. The base module 112 is further configured to be electricallycoupled to a power source (e.g., an electrical wire coming from anelectrical breaker box to the electrical wall box) and to one or morelight fixtures wired to the electrical box. Accordingly, the base module112 provides an interface between a power source, the light switchactuator 106, and one or more light fixtures. The base module includes aprocessor 140 and a circuit board 141 for managing the power supplied bythe power source and routed to the one or more light fixtures inaccordance with a light setting selection identified via the lightswitch actuator I 06 or the tactile display 104.

One or more of the processor 130 on the printed circuit board 138 andthe base module processor 140 may include wireless links forcommunication with one or more remote electronic devices such as amobile phone, a tablet, a laptop, another mobile computing device, oneor more other lighting control devices 100 or other electronic devicesoperating in a location. In certain implementations the wireless linkspermit communication with one or more devices including, but not limitedto smart light bulbs, thermostats, garage door openers, door locks,remote controls, televisions, security systems, security cameras, smokedetectors, video game consoles, robotic systems, or other communicationenabled sensing and/or actuation devices or appliances. The wirelesslinks may include BLUETOOTH classes, Wi-Fi, Bluetooth-low-energy, alsoknown as BLE (BLE and BT classic are completely different protocols thatjust share the branding), 802.15.4, Worldwide Interoperability forMicrowave Access (WiMAX), an infrared channel or satellite band. Thewireless links may also include any cellular network standards used tocommunicate among mobile devices, including, but not limited to,standards that qualify as 1G, 2G, 3G, or 4G. The network standards mayqualify as one or more generation of mobile telecommunication standardsby fulfilling a specification or standards such as the specificationsmaintained by International Telecommunication Union. The 3G standards,for example, may correspond to the International MobileTelecommunications-2000 (IMT-2000) specification, and the 4G standardsmay correspond to the International Mobile Telecommunications Advanced(IMT-Advanced) specification. Examples of cellular network standardsinclude AMPS, GSM, GPRS, UMTS, LTE, LTE Advanced, Mobile WiMAX, andWiMAX-Advanced. Cellular network standards may use various channelaccess methods e.g. TDMA, TDMA, CDMA, or SDMA. In some embodiments,different types of data may be transmitted via different links andstandards. In other embodiments, the same types of data may betransmitted via different links and standards.

FIG. 2A shows the lighting control device 100 of FIG. 1A mounted on awall 200. As demonstrated in FIG. 2A, the base module 112 is not visibleupon installation of the lighting control device 100 in view of the wallplate cover 108. Because the wall plate cover 108 attaches to the basemodule 112, the wall plate cover 108 appears to be floating on the wall200. The lighting control device 100 may be activated by a user 103interacting with the outer actuation surface 122 and the tactile display104.

FIGS. 2B and 2C illustrate multi-switch configurations of multiplelighting control devices. FIGS. 2B and 2C illustrate two switch andthree switch embodiments, respectively, where the lighting controldevices 202 and 203 each include a light switch actuator 106 as well asauxiliary switches 204 and 208, as well as 2 and 3 base modules 112,respectively.

FIGS. 3A-3F illustrate a lighting control device transitioning throughvarious lighting settings and a room having lighting fixtures controlledby the lighting control device.

In FIG. 3A, the lighting control device 300 is connected to a basemodule positioned behind the wall plate 308. The lighting control device300 includes a dynamic light switch actuator 306, operable in a mannersimilar to the light switch actuator discussed in connection with FIGS.1A-2C, and an auxiliary light switch actuator. As demonstrated in FIG.3A, the unilluminated outer actuation surface 322 of the light switchactuator 306 is inactive and not energized. In response to a user 103moving the actuation surface 322 of the light switch actuator 306, thelight switch actuator 306 begins to become energized, as shown in FIG.3B. The energization or activation of the light switch actuator 306 issignaled by the power light indicator 305 and by full lighting settingicon 351. As shown in FIG. 3C where the icon 351 is fully lit (ratherthan partially lit as in FIG. 3B), the light switch actuator 306 isfully energized. In this particular configuration, the primary lights309 and 310 are illuminated at full power. FIG. 3D shows the transitionbetween lighting settings. As demonstrated in FIG. 3D, this transitionis facilitated via user 103 completing swiping gesture 312 across thetactile display 304 and along the actuation surface 322. As the usercompletes the gesture 312, the icon 351 is swiped from the tactiledisplay 304 as the tactile display toggles to a new light setting shownin FIG. 3E. The new light setting shown in FIG. 3E is represented oridentified by the dinner icon 352. The new light setting shown in FIG. 3has the light fixture 309 powered down and has caused lamp 316 andsconces 318 to become illuminated to change the lighting scene in theroom. The change in the light setting causes a change in distribution ofpower to certain lighting fixture based on the selected lightingsetting. The light switch actuator 306 may be pre-programmed with aplurality of lighting settings or may be configured with particularlighting settings as specified by the user 103. A further swipinggesture 315 shown in FIG. 3F or a different gesture are used totransition from the lighting setting of FIG. 3F represented by icon 352to a further lighting setting.

FIG. 4 provides a flow diagram of operations of a system for controllinga lighting control device and, more particularly, control operations ofa control system, such as processor 130 configured to control thelighting control device 100 or 300, in accordance with variousembodiments of the present invention. At 401, the tactile display housedin the light switch actuator is activated by moving the light switchactuator, for example by moving the actuation surface of the lightswitch actuator. At 402, the light fixtures electrically coupled to thelight switch actuator via a base module are powered as the movement ofthe light switch actuator causes a contact component to move into a newposition and thereby permit or cause an electrical flow path between apower source and the light fixture(s) to be closed. The tactile displayhoused in the light switch actuator is moved contemporaneously with theactuation surface. At 403, a lighting setting selection request isreceived via the tactile display, for example by a particular motion ormotions on the tactile display. The lighting setting selection requestidentifies a lighting setting from among a plurality of lightingsettings. A user may swipe multiple times to toggle through theplurality of lighting settings or may conduct a specific motion thatcorresponds to a particular lighting setting including, but not limitedto, a half swipe and tap to achieve a light intensity of all theconnected light fixtures at half of their peak output. The lightingsettings identify distinct power distribution schemes for one or morelight fixtures connected to the light switch module. At 404, a powerdistribution scheme is identified. At 405, the identified powerdistribution scheme is transmitted, for example by the base moduleresponding to control signals from the light switch actuator, to adjustone, some, or all of the lights based on the power distribution schemecorresponding to the lighting setting selected. The power distributionschemes or profiles may be stored in a memory device of the lightingcontrol device. In certain embodiments, the power distribution schemesmay be adjusted to account for other parameters such as ambient lightingfrom natural light or an unconnected source. In certain embodiments thepower distribution schemes may be adjusted based on one or more othersensor parameters. In particular embodiments, the lighting setting maybe adjusted by automation based on time of day, sensed parameters suchas light, temperature, noise, or activation of other devices including,but not limited to, any electronic device described herein.

FIG. 5 shows a flow diagram of a system for remotely operating alighting control device. In particular embodiments, the lighting controldevice 100 or 300 may be operable from a remote device if the actuatorswitch is activated or energized. In such instances, the remote devicemay include one or more computer program applications, such as system500, operating on the device to communicate with and control thelighting control device. Accordingly, at 501, the control system 500initiates a connection module to generate a communication interfacebetween a mobile electronic device and a light switch module. Theconnection module may cause the remote device to send one or morewireless transmissions to the lighting control device via acommunication protocol. At 502, the control system 500 causes the remotedevice to generate a display of icons on a display device of the mobileelectronic device to facilitate selection of a lighting setting. At 503,the control system 500 receives a lighting setting selection based onthe user selecting a particular icon. At 504, a transmission modulecauses the lighting setting selected to be transmitted to the lightingcontrol device so that the light switch module and/or the base modulecan cause the power distribution scheme corresponding to the lightingsetting to be transmitted to the lighting fixtures. The tactile displayof the lighting control device may be updated in concert with receipt ofthe lighting setting to display the icon selected on the mobileelectronic device and corresponding to the lighting setting selected onthe tactile device.

FIG. 6 illustrates a flow diagram of a system for remotely configuringoperations of a lighting control device. The remote device may includedevices including, but not limited to a mobile phone, a mobile computingdevice or a computing device remote from the light control device. At601, the mobile electronic device generates a communication interfacewith the light switch module. At 602, a light fixture identificationmodule initiates a sensor-based protocol to identify a parameterassociated with one or more light fixtures connected to the light switchcontrol module. At 603, a display selection module causes a display ofan icon to appear on a display device of the mobile electronic device.At 604, a lighting setting configuration module allows a user to createa power distribution scheme or profile for the light fixtures identifiedbased on the identified parameters and a user specified input related tolight intensity. At 604, a storage module is used to the store the powerdistribution scheme and associate a particular lighting setting iconwith the power distribution scheme. At 605, a transmission moduletransmits the power distribution scheme and the associated icon to thelight switch control module.

FIG. 7A illustrates a simple diagram of a multi-way circuit 700 havingtwo base modules Base A and Base B that may be used in multi-way schemesfor lighting control devices. The multi-way circuit 700 may operate witha controller, such as switch controller 802, in conjunction with thebase modules, such as base lighting control module 812, of a lightingcontrol system, such as lighting control system 800, to provide a fullyfunctional, multi-way toggle circuit, even when the switches installedin the base module are not paired or in their off modes. As used herein,the multi-way toggle circuit 700 can be defined (configured) as follows:if a button in the circuit is pressed (indicating a desire to change aload state), then a load coupled to the circuit toggles its statebetween on and off.

FIG. 7B is a simplified state diagram 720 illustrating states of eachbase module of the multi-way circuit 700, wherein the states include:

-   -   1. Default state. Transistors, such a field effect transistors        (FETs) of the base modules Base A and/or Base B are off and the        load is off.        -   a. The Default state 1 is left when the base module or its            switch receives a button press (go to Measure state 2) or            when it recognizes the load is energized (go to Wait state            3).    -   2. Measure state. The FETs of the Base module are on, energizing        the load.        -   a. During the Measure state, the Base module energizes the            load and measures the RMS current at every line cycle. This            state is left when the Base module detects the pre-defined            current pulses (go to Default state 1).    -   3. Wait state. During the Wait state, the FETs of the Base        module are off, but the switch recognizes the load is energized.        -   a. The Wait state is left when the base module or its switch            receive a button press (go to Transmit state 4).        -   b. Alternatively, the Wait state may function as a temporary            check when leaving the Default state 1 to proceed to the            Transmit state 4 or Measure state 2.    -   4. Transmit state. During the Transmit state, the Base module        pulses its FETs to notify other Base modules to turn off load.        -   a. The Base module automatically leaves the Transmit state            to return to the Default state 1 after the pre-defined            current pulses have been sent out.

Those skilled in the art will understand that there are more states thatmay be implemented in accordance with certain embodiments, but thestates described herein provide specific examples. For example, if Basemodule A receives a button press, then it will transition from theDefault state 1 to the Measure state 2. The Base module B will noticethat the load is now energized by examining its voltage detectionwaveforms.

FIG. 7C illustrates an embodiment of exemplary waveforms 750 of the basemodules of the multi-way circuit. Essentially, if the LD_DET waveform isin-phase with the LN_DET waveform, then the load is already energized(i.e. Load is shorted to Line). If the Base module B receives a buttonpress when it sees the load is energized, then instead of simply turningon its FETs to energize the load, the module will send a series ofcurrent pulses to the Base module A to signal to Base module A that itneeds to turn off its FETs. The Base module B creates these currentpulses by turning its FETs on and off to share the load current with theBase module A. If Base module B turns on its FETs, then Base module Awill see its current drop by half.

FIG. 7D illustrates another embodiment of exemplary waveforms 770 of thebase modules of the multi-way circuit. Here, pre-defined current pulsesare determined (i.e., FETs on for 1 complete line cycle, then off for 1complete line cycle) shown 3 times. Since the Base module A measures theline cycle root mean square (RMS) current, it will see the RMS valuedrop by half for 1 cycle, then return to full for another, and so onuntil it determines that this is a message from Base module B (or basemodules C or D, depending on the number of Base modules in the multi-waycircuit), and then Base module A will turn off its FETs and return toDefault state 1.

FIG. 8 is a schematic of a lighting control system 800 configured toexecute certain lighting control operations described herein. Thelighting control system 800 illustrates lighting control systemcomponents that can be implemented with a lighting control systemincluding an air gap system as described herein. The lighting controlsystem 800 is depicted separated into a base lighting control module 812(which may be configured in a manner similar to base module 112) and aswitch module or switch controller 802 (which may be configured in amanner similar to switch module 102). As described herein, the switchmodule 802 can include a tactile interface, operable via the graphicaluser interface module 852, and a switch actuator, such as the tactiledisplay 104 and the light switch actuator 106 described herein. Theswitch module 802 houses a processor 850, which may be configured tosend commands to microcontroller 840 and receive inputs from themicro-controller 840 to control the operation of a transformer 818, apower isolator and an AC to DC converter 814 (which may include aflyback converter), and a dimmer 813 based on a MOSFET , a voltage andcurrent sensor 816. In some embodiments, the base lighting controlmodule 812 may include a TRIAC based dimmer The power isolator 814separates the analog AC current from the low power or DC digitalcomponents in the base lighting control module 812 and the switch module802. The power isolator 814 may provide power inputs to the switchcontrol module 802 via a power module 853. Power module 853 includespower circuitry configured to regulate the flow of power from the basemodule 812 to the switch controller module 802 including directing powerto one or more of the modules in the switch controller module 802. Theswitch module 802 also houses a communication module, which can includeone or more antennae or other wireless communication modules. The switchmodule 802 also houses a sensor module, which can include one or moresensors, such as a light sensor, a camera, a microphone, a thermometer,a humidity sensor, and an air quality sensor. The processor 850, iscommunicably coupled with one or more modules in the switch module 802to control the operation of and receive inputs from those modules, forexample to control modulation of the flow of electrical energy to alighting circuit of a light fixture 824 connected to the base lightingcontrol module 812.

The base lighting control module 812 includes a ground terminal 830 forgrounding various electrical components container in the module 812. Thebase light control module 812 includes a neutral terminal 828 forconnecting to a neutral wire, a line terminal 826, and a load terminal822. As shown in FIG. 8, the voltage and current sensor(s) are coupledto the load line to detect changes in the voltage or current along theline carrying power to one or more light fixtures 824 connected to thelighting circuit (750). The base lighting control module 812 alsoincludes a controller 840 communicably coupled to the processor 850. Thebase lighting control module 812 also includes LED indicator lights 842and 841 for indicating information regarding the status of the baselighting control module 812. For example, in some embodiments LEDindicator light 841 can indicate if a neutral wire is connected whileLED indicator light 842 can indicate if a 3-way connection is connected.

FIG. 9 describes an implementation of lighting control system 900 thatincludes multiple lighting control subsystems that are distributed overa building (e.g., house, office etc.), for example, in different roomsof the building. In the implementation of the lighting control system900 illustrated in FIG. 9A, rooms 902 a-d have distinct lighting controlsystems. For example, the lighting control system of room 902 a includeslighting control device 904 a, lighting circuit 910 a, light sensors 906a and motion sensors 908 a. The lighting control system 900 can includea central lighting control device 904 that serves as a central controlfor the lighting control system 900. In certain embodiments, the centrallighting control device 904 can include a lighting control system suchas system 100 or 800.

The lighting control system of room 902 a, which comprises lightingcontrol device 904 a, light sensor 906 a, motion sensor 908 a andlighting circuit 910 a, is discussed. However, the concepts andapplications discussed are not limited to the lighting control system inthe room 902 a and can be generally applied to lighting control systemsin other rooms (e.g., 902 b-d) or lighting control subsystems that maydistributed over more than one room.

The light sensor 906 a is configured to detect ambient light (which caninclude natural light and/or light from a light fixture connected to thelighting circuit 910 a), for example by converting the electromagneticenergy (e.g., photon energy) into an electrical signal (e.g., a currentor a voltage signal). The electrical signal can be communicated to thelighting control device 904 a. The light sensor 906 a can include one ormore photo-resistors, photodiodes, charge coupled devices etc. The lightsensor 906 a can include a light filter that preferentially allowscertain frequencies of light to be transmitted and therefore detected bythe light sensor 906 a. For example, the light filter can be configuredto transmit frequencies that correspond to the light emanating from thelighting circuit 910 a. This can allow the light sensor (e.g. 906 a) topreferentially detect light from the lighting circuit 910 a whilefiltering out light generated by other sources. For example, if thelight sensor is located in a room that receives ambient natural light(e.g., daylight), the light sensor can substantially filter out theambient natural light and primarily detect light from the lightingcircuit 910 a. The light sensor 906 a can also be configured toefficiently and accurately detect a range of light intensities, forexample, the range of intensities that can be produced by the lightingcircuit 910 a. This can allow the light sensor 906 a to efficiently andaccurately detect light for various intensity settings of the lightingcircuit 910 a.

The motion sensor 908 a can be configured to detect motion in the room902 a. For example, the motion sensor can detect movement of an occupantin the room 902 a. The motion sensor 908 a can include one or more ofpassive sensors (e.g., passive infrared (PIR) sensor), active sensors(e.g., microwave (MW) sensor, ultrasonic sensors etc.) and hybridsensors that include both passive and active sensor (e.g., DualTechnology Motion sensors,). The passive sensors do not emit any energyand detect changes in energy of the surrounding. For example, a PIRsensor can detect infrared energy emitted by the human body (due to thetemperature associated with the human body). Active sensors, on theother hand, emit electromagnetic or sonic pulses and detect thereflection thereof. For example, MW sensor emits a microwave pulse anddetects its reflection. Hybrid sensors can include both active andpassive sensors and therefore motion can be sensed both actively andpassively (hybrid sensing). Hybrid sensing can have several advantages,for example, the probability of false positive detection of motion canbe smaller in hybrid sensors compared to active/passive sensors.

The lighting control device 904 a is configured to communicate with thelight sensor 906 a and motion sensor 908 a. The motion sensor 908 a cansend a notification signal to the lighting control device 904 aconveying that motion has been detected in an area proximal to thelighting circuit 910 a, for example, in the room 902 a. The light sensor906 a can send a notification signal to the lighting control device 904a conveying that light emanating from the lighting circuit 910 a hasbeen detected. Additionally, the notification signal can includeinformation about the properties of the detected light, e.g., intensity,bandwidth etc. The lighting control device 904 a can store datarepresentative of the notification signals received from the motion andlight sensors in a device database. The lighting control device 904 acan include a clock and/or a timer that allows the lighting controldevice 904 a to track the time and/or duration of the received signalsfrom the light sensor 906 a and motion sensor 908 a. The tracking timeand/or duration information can be also be stored in the devicedatabase.

The lighting control device 904 a can be configured to receive andtransmit data through the internet. The lighting control device 904 acan, for example, infer information about ambient natural light fromdata about the weather conditions, daylight hours etc. from onlinedatabases (e.g., databases of weather.gov, gaisma.com, noaa.govwunderground.com etc.). For example, the received data can includeinformation about the sunrise and sunset times in the geographical areaassociated with the lighting control system 900 and the time of theyear. Based on this, the lighting control circuit 904 a can infer thetime period during which no ambient natural light is available. Inanother example, the received data can contain information about theweather conditions. The lighting control circuit 904 a can infer, forexample, that overcast conditions can lead to reduction in naturalambient light. The lighting control device 904 a can save the dataand/or inferred information in the device database. This can allow thelighting control device 904 a to infer patterns between the usage of thelighting circuit 910 a and ambient natural light conditions.

The lighting control device 904 a can be configured to determine one ormore properties of the lighting circuit 910 a. For example, device 904 acan determine the type (e.g., incandescent, fluorescent, LED, halogen,high intensity discharge, full spectrum, UV, black light, antique,vintage) and the wattage of the light bulbs associated with the lightingcircuit 910 a. The light control device 904 a can also search onlinedatabases for information about the detected light bulbs. For example,the lighting control device 904 a can download specifications (e.g.,information about voltage, wattage, luminescence, dimmability, averagelife etc.) from online databases of the manufacturers of the detectedlight bulb. The lighting control device 904 a can also downloadinformation related to the light and motion sensors, for example,drivers associated with the light and motion sensors. The determinedproperties and the downloaded information about the lighting circuit 910a can be stored in the device database.

The lighting control device 904 a can be configured to receive dataand/or instructions from communication device 920 (e.g., cellphone,laptop, iPad, input device such as keypad, touch screen etc.).Additionally, or alternately, communication device 920 can be an inputdevice (e.g., keypad, touchscreen etc.). For example, the computationdevice 920 may provide instructions for the operation of the lightingcontrol device 904 a. Based on the instruction, the lighting controldevice 904 a can switch on/off one or more light bulbs in the lightingcircuit 904 a. The computation device 920 can also instruct the lightingcontrol device 904 a to change the operation parameters of the lightingcircuit 910 a. For example, the lighting control device 904 a can beinstructed to increase/decrease the brightness of the lighting circuit904 a (e.g., by increasing/decreasing the power supplied to the lightingcircuit). The communication device 920 can instruct the lighting controldevice 904 a to perform one or more of the aforementioned functions at acertain time or after a certain period of time. For example, thecommunication device 920 can instruct the lighting control device 904 ato set up a timer at the end of which a desired function is performed.Through the communication device 920, information related to thelighting control system 900 can be conveyed to the lighting controldevice 904 a. For example, a user can input the room-types (e.g.,bedroom, kitchen, living room etc.) of the rooms 902 a-d. The user canshutdown one or more the lighting control subsystems in room 902 a-d fora desired period of time, for example, when the user will be away for avacation. The communication device 920 can communicate with the lightingcontrol device 904 a using short-range wireless technology (Bluetooth,Wi-Fi etc.), through a cellular network and/or a physical connection(e.g., Ethernet cable). The data and/or instruction received by thelighting control circuit 904 a from the communication device 920 can bestored in the device database. The time at which the data and/orinstruction were received can also be stored in the device database.

The lighting control device 904 a can be configured to communicateinformation to the communication device 920 and/or an output screen. Forexample, the lighting control device 904 a may communicate theoperational parameters associated with the lighting circuit 910 a (e.g.,brightness of the lighting circuit 910 a, tentative time at which thelighting circuit 910 a will be turned on/off, duration of operation ofthe lighting circuit 910 a etc.). The lighting control device 904 a cancommunicate notification signal from the light sensor 906 a and motionsensor 908 a to the communication device 920. For example, communicationdevice 920 can be notified that motion or light has been detected inroom 902 a.

The central lighting control device 904 can communicate with thelighting control subsystems distributed over the building (e.g., rooms902 a-d), and provide a central control for the lighting control system900. The central lighting control device 904 can control the operationof light sensors 906 a-d, motion sensors 908 a-d, lighting circuits 910a-d and lighting control devices 904 a-d. For example, the centrallighting control device 904 can instruct the lighting control device 904a to change the operating parameters of the lighting circuit 910 a. Thecentral lighting control device 904 can also receive notificationsignals from light sensors 906 a-d and motion sensors 908 a-d, andcommunication device 920.

The central lighting control device 904 can include a central devicedatabase. Data stored in device databases associated with lightingcontrol devices 904 a-d can be transferred, for example, periodically,to the central device database. In some implementation, the centrallighting control device can request specific information from the devicedatabases of lighting control devices. For example, the central controldevice 904 can request the lighting control device 904 a for informationrelated to one or more of light sensors 906 a, motion sensors 908 a,instructions from communication device 920, etc. FIG. 9B illustratesanother implementation of the lighting control system 900. In thisimplementation the central light control device 904 also operates as the“lighting control device” for the lighting control subsystem associatedwith room 902 a (which includes light sensor 906 a, motion sensor 908 aand lighting circuit 910 a).

FIG. 10 illustrates an implementation of the central lighting controldevice 904 as described in FIG. 9B. The central lighting control device904 includes lighting circuit system 1010, controller 1020 andcommunication system 1030. The controller 1020 can control the operationof and receive data from the lighting circuit system 1010 andcommunication system 1030. The controller 1020 includes a processor 1022and a storage device 1024. The processor is configured to runapplications that control the operation of the lighting control system900, and the storage device 1024 can store data related to the lightingcontrol system 900 (e.g., central device database, device databaseetc.).

The lighting circuit system 1010 can transmit electrical power to anddetect response of the lighting circuit 910 a. The lighting circuitsystem 1010 can include a power circuit 1014 that can supply power tothe lighting circuit 910 a, and a detector circuit 1012 that can detectthe response of the lighting circuit 910 a. The power circuit 1014 caninclude a tunable voltage/current source that can supply an inputvoltage/current signal to the lighting circuit 910 a. The detectorcircuit 1012 is configured to detect a response of the lighting circuit910 a that can include one or more of current, voltage and impedanceresponse. In some implementations, the detector circuit 1012 may includea voltage sensing circuit that can detect a voltage response (e.g.,voltage across the lighting circuit 910 a) or a current sensing circuitthat can detect a current response (e.g., the current flowing into thelighting circuit 910 a). The power circuit 1014 can also supply power tothe light sensor 906 a and the voltage sensor 908 a.

The communication system 1030 is configured to communicate with lightsensor 906 a, motion sensor 908 a, and lighting control devices (e.g.,910 a-d in FIG. 9A, 910 b-d in FIG. 9B). For example, the communicationsystem 1030 (e.g., antenna, router etc.) can transmit instructions(e.g., instruction to detect light/motion) from the controller 1020 tothe light sensor 906 a and/or motion sensor 908 a. The instructions canbe transmitted wirelessly in the 2.4 GHz ISM band using various wirelessradio technologies (Wi-Fi, Bluetooth, Low Power Radio (LPR) etc.).Additionally, or alternately, the instructions can be transmitted in theform of an electrical signal (e.g., current signal, voltage signal) oroptical signal through a physical connection (e.g., transmission line,Ethernet cable etc.). The communication system 930 can be configured toreceive notification signals (e.g., through the channels of instructiontransmission described above) from the light sensors 906 a and/or motionsensors 908 a and convey the notification signal to the controller 1020.

The communication system 1030 can also be configured to communicate withcommunication device 920, for example, through a cellular network,wireless radio technology etc. The communication system 1030 caninclude, for example, a router that allows it to communicate through theinternet with websites and online databases. For example, the controller1020 can instruct the communication system 1030 to access the website ofa light bulb manufacturing (e.g., light bulb in the lighting circuit 910a) and download the relevant specifications. The communication system1030 can also, for example, download software (e.g., drivers) that canallow the controller 1020 to communicate with the light sensors 906 aand motion sensors 908 a. The communication system 1030 can alsodownload updated operating systems for the controller 1020.

The lighting control device 904 can control the operation of lightingcircuits 910 a-d based on notification signals from the light sensors906 a-d and motion sensors 908 a-d. For example, if the lighting circuit910 a has been switched on and no motion is observed by the motionsensor 908 a for a predetermined period of time, the control device 904can automatically switch off the lighting circuit 910 a. The controldevice 904 can make the determination that the lighting circuit 910 ahas been switched on based on notification signal from the light sensor906 a and/or the response from the detector circuit 1012. The period oftime between the last detected motion and the time at which the lightingcircuit 910 a is switched off can be based on, for example, an inputprovided by a user through the communication device 920. This period oftime can be different for different rooms. For example, the period oftime can be longer for the room 902 a (e.g., bedroom) compared to theroom 902 b (e.g., a bathroom).

The lighting control system 900 can be configured to control theoperation of the lighting circuits 910 a-d based on analysis of thebehavior of one or more users of the system 900 and data acquired by thesystem 900. The behavior analysis can include, for example, patternrecognition of the notification signals from the light sensors 906 a-dand motion sensors 908 a-d, instructions provided by the user throughcommunication device 920 and information obtained by lighting controldevice 904 from online databases. For example, the central lightingcontrol device 904 can be notified by the light sensor 906 a that thelighting device 910 a is switched off at approximately a certain timeduring the weekdays and at approximately a different time during theweekends. Based on this pattern, the lighting control device 904 can setswitch off times, which are different for weekends and weekdays, forautomatically switch off the light 910 a. Automatic switching off thelight 910 s can be suspended if motion is detected by motion sensor 908a, and notification can be sent to the communication device 920.

The control device 904 can also include information obtained from onlinedatabases in its behavioral analysis of the users. For example, thecontrol device 904 can be notified that the user switches on the light910 a in the mornings of certain days in the year. The device 904compares this behavior with the weather conditions (known through onlinedatabases) and determines that the light 910 a is switched on in themornings of days when the sky is overcast. Based on this pattern, thecontrol device 904 can automatically switch on the light 910 a on dayswhen the sky is overcast. Additionally, the control device 904 may learnthat the weather conditions effect the operation of lighting circuit 910a but not of lighting circuit 910 b. This may arise from the fact theroom 902 a, associated with lighting circuit 910 a, has windows andreceives natural ambient light, while room 902 b, associated withlighting circuit 910 b, does not have windows and does not receivenatural ambient light. The control device 904 can infer that theoperation of lighting circuit 910 b is independent of weatherconditions. In some implementations, the control device 904 can changethe operating parameters of lighting circuit 910 a based on weatherconditions. For example, the control device 904 can change thebrightness setting of the lighting circuit 910 b based on the weatherconditions.

FIG. 11 illustrates the controller 1020 including the processor 1022 andthe storage device 1024 and configured to execute light control module1102. The light control module 1102 can collect, store and analyze data,and determine the operation of a lighting circuit (e.g., lightingcircuit 910 a). The light control module 1102 can include a datacollection module 1104, system control module 1106, and patternrecognition module 1108. The data collection module can collect data(e.g., data from online databases, detector circuit 1012, communicationdevice 920, notification signals from light sensors 906 a-d and motionsensors 908 a-d etc.) from the communication system 1030 and store thedata in the central device database 1112 in storage device 1024. Thesystem control module 1106 controls the operation of lighting circuitsystem 1010. For example, system control module 1106 can instruct thepower circuit 1014 to change the electrical power supplied to thelighting circuit 910 a. The system control module 906 can determine,based on voltage/current response of the lighting circuit 910 a measuredby the detector circuit 1012, the type of light bulbs (e.g.,incandescent, fluorescent, LED, halogen, high intensity discharge, fullspectrum, UV, black light, antique, vintage) therein and store thisinformation in the central device database 1112. The system controlmodule 1106 can also control the operation of the light sensors 906 a-dand motion sensors 908 a-d. For example, it can instruct the light andmotion sensors to start or suspend detection of light and motionsignals. The pattern recognition module 1108 can include machinelearning techniques that use data in the central device database 1112 as“training data” to infer patterns based on which the operatingparameters for the lighting circuits 910 a-d can be determined.
